The Role of Talcum Powder in Automobile Lightweight


In recent years, the automobile industry has mainly revolved around the theme of "lightweight, energy saving, high speed, safety, comfort and low cost", among which lightweight is the key. Compared with the specific gravity of several materials commonly used in automobiles: A3 steel 7.6, brass 8.4, aluminum 2.7, while the specific gravity of general plastics is only 0.9-1.6, and the specific gravity of glass fiber reinforced composite materials is also within 2. Therefore, although plastic is not as strong as carbon fiber, metal and other materials, plastic has the best lightweight effect, high specific strength, and excellent processability. It is the preferred material for lightweight automobiles. The use of plastics can reduce the weight of parts by about 40%, and the power, comfort and safety of the car can be improved.


 The polymer materials used in the automobile industry cover a wide range. For example, PP, ABS and their alloys are mainly used for interior and exterior parts, PA materials are mainly used for power, chassis parts and structural parts, PC, POM and other materials are mainly used for electronic and electrical parts and structural parts, and rubber materials are mainly used for automobile tires, rubber tubes, transmission belts, shock absorbing blocks, sealing strips, etc. At present, the amount of plastic used in domestic automobiles accounts for about 10% of the vehicle's own weight, of which the largest variety is PP, and the others are PVC, PU, ABS, PE, PA, etc.


As an important filling component in modified PP, talc has excellent physical and chemical properties, such as lubricity, adhesion resistance, flow aid, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, soft, good gloss, strong adsorption and so on. The addition of talcum powder can change a variety of properties of plastics, such as molding shrinkage, surface hardness, flexural modulus, tensile strength, impact strength, thermal deformation temperature, molding process and product dimensional stability.

Yuan Lei's Little Knowledge | Performance Requirements and Types of Fillers for Coatings


Fillers in coatings are usually white or slightly colored pigments with a refractive index less than 1.7. It has the basic physical and chemical properties of pigments used in coatings, but due to its refractive index being similar to the film-forming material, it is transparent in coatings and does not have the coloring and covering power of coloring pigments. It is an indispensable pigment in coatings.

Yuan Lei's Little Knowledge | Application Effects of Different Mineral Powder Materials in Coatings


In architectural coatings, commonly used mineral materials include barium sulfate, calcium carbonate, kaolin, mica powder, talc powder, quartz powder, silica micro powder, transparent powder, glass powder, wollastonite powder, etc. Reasonable application of various mineral materials can effectively improve or enhance the performance of coatings. Let's take a look at the application of different mineral materials in coatings.

Yuan Lei's Little Knowledge | Characteristics of Mineral Materials


Mineral materials refer to the material products obtained by processing and transforming natural minerals (mainly non-metallic minerals) or rocks as the main raw materials, or minerals or rocks that can be directly used as materials and aim to utilize their main physical and chemical properties. This meaning mainly includes the following four aspects: first, natural minerals and rocks that can be directly utilized or processed to be utilized; Secondly, finished or semi-finished materials made mainly from natural non-metallic minerals and rocks through physical and chemical reactions; Thirdly, artificially synthesized minerals or rocks; Fourthly, the direct utilization targets of these materials are mainly their own physical or chemical properties, not limited to individual chemical elements.
